What Are Prepositions?
A preposition is a word that connects a noun, pronoun, or noun phrase to other parts of a sentence. Prepositions typically convey ideas related to location, timing, direction, or relationship. In essence, they act as small but mighty connectors that show how various elements in a sentence relate to one another.
For instance:
- I left my book on the table.
- Here, “on” shows the relationship between “book” and “table.”
- She walked through the park.
- Here, “through” indicates direction and location in relation to “park.”
Prepositions are critical for constructing logical, clear sentences. Without them, readers would struggle to understand when or where events occur, or how different parts of a sentence relate. This guide will help you recognize and use these crucial words properly.
Why Prepositions Matter
If you’re a student, professional writer, businessperson, or just someone striving to communicate more effectively, prepositions can make or break your sentence structure. Accurate use of prepositions adds precision to your message, preventing misunderstandings and clarifying intricate details. This precision is especially important in:
- Academic Writing: Prepositions help explain research contexts or data points (e.g., “The experiment was conducted in the laboratory”).
- Professional Correspondence: Business emails, memos, and reports rely on clarity (e.g., “Please review the document attached to this email”).
- Everyday Communication: Even casual text messages or social media posts benefit from correct prepositions (e.g., “We’ll meet at the cafe at noon”).
Learning how to use the right preposition at the right time is one of the most effective ways to polish your English writing and speaking skills.
Types of Prepositions
Prepositions come in different forms, each serving a unique purpose. The five main categories include:
- Prepositions of Time
- Prepositions of Place
- Prepositions of Direction
- Prepositions of Agent or Instrument
- Phrasal Prepositions
Let’s explore each type in detail, complete with useful preposition examples.
Prepositions of Time
Prepositions of time indicate when something happens. Common examples include:
- At: used for specific times or moments.
- I wake up at 7 a.m.
- On: used for days and dates.
- They arrived on Monday.
- In: used for months, years, seasons, and longer periods.
- The event takes place in December.
- By: used to indicate a deadline.
- Submit your assignment by Friday.
- From… to…: used for starting and ending times.
- The shop is open from 9 a.m. to 5 p.m.
- Before/After: reference points in time.
- Let’s meet before noon. / Let’s talk after class.
Keep in mind the time format you are using. For example, “in the morning,” “in the afternoon,” and “in the evening” are correct, but we say “at night” to indicate nighttime as a general point in time.
Prepositions of Place
Prepositions of place specify where something or someone is located. Frequently used examples are:
- In: indicates something is inside an enclosed space.
- She is in the kitchen.
- On: used when something is on a surface.
- There’s a pen on the table.
- At: denotes a general location or point.
- Meet me at the corner.
- Under: used to describe something below another object.
- Your keys are under the couch.
- Above: suggests that one object is higher than another but not necessarily directly over it.
- A ceiling fan hangs above the table.
- Over: something that is directly above something else, often implying covering.
- We flew over the mountains.
- Between: indicates a location in the middle of two objects or points.
- He sat between his two friends.
- Among: used when talking about something in the midst of a group.
- She found her scarf among her other belongings.
Use these prepositions to paint a clear picture of spatial relationships. “In” typically indicates an enclosed area, “on” refers to a surface, and “at” is used for a point in a larger area.
Prepositions of Direction
Prepositions of direction show movement or motion toward or away from something. Some of the most common are:
- To: indicates a movement from one place to another.
- We walked to the store.
- Into: shows movement from the outside to the inside.
- She poured the juice into the glass.
- Out of: describes movement from inside to outside.
- He stepped out of the car.
- Toward: implies moving in the direction of something.
- She moved toward the exit.
- Through: suggests movement across an entire area, often enclosed.
- He jogged through the park.
- Along: indicates movement in line with something.
- They strolled along the river.
These prepositions make action verbs clearer by describing the path or direction the action takes. If you visualize the motion, you can pick the correct preposition easily.
Prepositions of Agent or Instrument
Prepositions of agent or instrument indicate “by whom” or “with what” an action is performed. Key words include:
- By: used to denote the doer of an action.
- The sculpture was made by a local artist.
- With: used to denote the tool or method used.
- He wrote the letter with a pen.
- Via: implies traveling or sending through a specific route or means.
- She sent the message via email.
These prepositions clarify the manner in which an action is carried out, highlighting the agent, tool, or method behind it.
Phrasal Prepositions
Phrasal prepositions are multi-word phrases that function like single prepositions. Examples include:
- Because of: indicates reason or cause.
- He was late because of heavy traffic.
- In front of: points to a position ahead.
- We parked in front of the grocery store.
- On account of: another way to indicate a reason.
- They canceled the event on account of the storm.
- According to: means “based on” or “as said by.”
- According to the report, sales have increased.
- In spite of/Despite: shows contrast or concession.
- He finished the race in spite of his injury.
Learning these phrases expands your prepositional toolbox, allowing you to express more nuanced ideas in a single unit.

Common Mistakes with Prepositions
Even experienced writers mix up prepositions sometimes. Below are some of the most frequent errors and how to avoid them:
- Using “in” instead of “on” or “at”
- Incorrect: I have a meeting in Monday.
- Correct: I have a meeting on Monday.
- Explanation: “On” is the correct preposition for days, while “in” is for longer durations (months, years).
- Misplacing prepositions at the end of sentences
- This is less strict in modern English, but be mindful of context. Some sentences allow ending with a preposition.
- Which team do you support? (Correct usage, the question’s meaning is clear.)
- Confusing “to” and “for”
- Incorrect: I gave a present to you for your birthday. (While not grammatically disastrous, it sounds repetitive in some contexts.)
- Correct: I gave you a present for your birthday.
- Explanation: Use “to” when indicating direction or destination, but “for” when indicating the benefit or purpose.
- Forgetting the object of the preposition
- Incorrect: He jumped over.
- Correct: He jumped over the fence.
- Explanation: Many prepositions require a noun or pronoun to complete the idea.
- Using “of” incorrectly
- Incorrect: The reason is because of we left early.
- Correct: The reason is that we left early. or We left early because of the storm.
- Explanation: “Because of” requires a noun object (the storm), not a clause.
- “Between” vs. “Among”
- “Between” is for two separate items, whereas “among” is for more than two items.
- Incorrect: Choose among these two options.
- Correct: Choose between these two options.
Always check the context of the sentence when selecting a preposition. Doing a quick “mental test” of whether the relationship is about time, place, or direction can help you choose the correct preposition.
Advanced Tips for Using Prepositions Effectively
Once you’ve mastered the basics, there are more nuanced aspects of prepositions that can elevate your writing:
- Prepositions in Idiomatic Expressions
- Many idiomatic expressions in English rely on specific prepositions that don’t always follow logical rules. For example, “interested in,” “capable of,” “familiar with.”
- Learn these pairs (“adjective + preposition,” “verb + preposition,” etc.) to gain fluency.
- Prepositional Phrases as Adjectives and Adverbs
- A prepositional phrase can act as an adjective:
- The boy in the red shirt is my brother. (Modifies “boy”)
- A prepositional phrase can also act as an adverb:
- They arrived at dawn. (Modifies “arrived”)
- Recognize these functions to ensure proper sentence structure.
- A prepositional phrase can act as an adjective:
- Avoiding Preposition Overload
- Too many prepositional phrases can slow down your writing:
- In the morning of the first day of summer at the camp, we sang a song with joy and excitement.
- Consider simplifying for clarity:
- On the first morning of summer camp, we sang happily.
- Too many prepositional phrases can slow down your writing:
- Choosing Concise Alternatives
- Instead of saying “He walked in the direction of the library,” you can say “He walked toward the library.”
- Aim for brevity when it enhances clarity.
- Parallel Structure with Prepositions
- If you’re listing multiple items or actions that share the same preposition, be consistent:
- She is interested in fashion, in music, and in photography.
- Omitting or changing prepositions in parallel lists can cause confusion or awkwardness.
- If you’re listing multiple items or actions that share the same preposition, be consistent:
- Prepositions and Passive Voice
- Prepositions often accompany passive constructions (e.g., “The book was written by her.”).
